hello all, something occured to me - if i had a pair of old MOTM850s, how could i build an adaptor to use them as theremin controllers..? easy / difficult / worthy of a stooge panel..? cheers paul b

From: Sikorsky <vulture.squadron@...> something occured to me - if i had a pair of old MOTM850s, how could i build an adaptor to use them as theremin controllers..? easy / difficult / worthy of a stooge panel..? cheers paul b --LH-- The short answer is no. But, if you were looking to do something along the lines of a "Theremin-like" device (the one actually used by the Beach Boys in good vibrations), you could. Here is a link to a modern version of what has been loosely dubbed a "Tannerin" because the original one was built for the Beach Boys by Paul Tanner (I think I have the name right) http://www.prismnet.com/~tpolk/music/music.html Tom Built the modern one that Brian Wilson is/was using currently. I have spoken (e-mail) with Tom several times about making a kit for this controller. He is a busy guy and has never made the commitment to make that happen. But, as you can see, you are essentially controlling two pots. One for pitch (the slide along the top) and one for volume (out of site on the side I think). If someone wanted to DIY the box with the two pots, certainly a couple of pedal interfaces would be all the electronics you needed (as opposed to the self contained device Tom built). Clearly, the challenges are in the smooth slide operation of the arm that controls the pot, and to design the mechanics to produce a linear keyboard. What really appealed to me about this idea is that one could have multiple keyboards or indicating devices with various scales printed and swap them at will. Since the controller is continuous, the number of different tunings is limited only by your imagination of drawing the appropriate stop points for your slide pointer to point at. We need someone good with wood (hint, hint DH) to design and build these for us. But, for Theremin control, Harry Bissell's pitch to CV PCB has got to be the way to go. This was adapted from the Moog schematic (with permission) that comes with the Etherwave for CV outs for pitch and volume. I am ashamed to say I have had one of the PCBs for over a year and have done nothing with it. Larry H

hello all, actually, it also occured to me that my original posting was complete bollox i just got this idea that it might be a workable solution still - we could always paste bits of 2" magnetic tape to old records, hook up a couple of contacts, and put that through the 850 instead a half inch length of 2" tape measures 148k ohms / twelve inch length 760k heheh the sooner i finish these iomega jaz to cdrom transfers the better... cheers paul b

Speaking of ideas and pedal interfaces, I got a super idea from Al Wagner for mini ribbons (say 2-3 inches long) that I could make with my copper mesh quickly. Maybe a small walnut wood base to attach to your favorite spot. No electronics, just hook it to the pedal interface just like a pedal. I'll try to whip up the proto in the next week or so (gotta do the taxes first). Larry

hello all, so leading on from this - say i had an LDR attached to an 850 interface, the LDR is being, erm, modulated by a small candle flickering but the voltage swing is too minute to be useful... ...so does anyone know of a DC voltage expander, or indeed compressor/limiter that can be used in much the same way you use an audio expander/compressor/limiter..? cheers paul b (at it again)

Sound like you've been having a fun afternoon, while I've battling a Cognex vison inspection system for clear plastics. I've been thinking about using a 6 inch or so linear pot for something like this. Probably more money than most would want to spend, but I can take one from work to play with.

Dave, I can say without reservation I would buy one of these if you made it. It could be offered two ways. One with just the pots so you hook it to one or two 850s and off you go and also another with the all the electronics inside that has CV out for pitch and volume and gate. I would be happy to do the "electronics" part. I really like the Tom Polk designs with the keyboard overlays that can be replaced. The 1/2 circle thing on the Carlos page was interesting, and probably easier mechanically to build. However, I like the flat surface idea better. One of the things I liked about it was the volume lever on the side instead of a knob to turn. I think the spring return idea was pretty cool. I would want a way to over-ride the return to zero. And something maybe a little better than a rubber band for the spring return Oh, and the hand on the slide ought to have the ability to tap gates with one of the loose fingers. Crazy Larry

I rather liked the "remake" of the Ondes Martenot on the Analogue Systems site that Les Mizzell mentioned a week ago. It has a keyboard and a ring just in front of the keys, into which you would slide a thumb or finger. Really pricey, but looks interesting. URL is below for anyone who missed the post. The Tom Polk designs are also interesting, especially the prospect of a kit version for about $200. This seems quite inexpensive, considering the materials involved. I rather doubt it can be offered at this price. Scott http://www.analoguesystems.co.uk/Reviews/fconnection_review.htm "J. Larry Hendry" wrote:
